GRAIN-WEIGHING AND TALLYlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 320,383, dated June 16, 1885.

Application filed June 14, 1984. No model.)

To all whom it may concern Beit known that. I, ISRAEL H. MURDIOK, a citizen of the United States of America, residing at Hartford, in the county of Van Buren and State of Michigan, have invented certain new and useful Improvements in GraiirWeighing and Tallying Machines; and I do hereby declare the following to be a'full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention is an improved grain bagging and weighingdevice; and it consists in the construction and combination of parts hereinafter fully described, whereby the bags are readily filled and the filling operation of each bag automatically discontinued when the said bag contains its predetermined amount of grain.

The said invention consists, further, in the improved devices and appliances for adjusting and regulating the amount of grain to be deposited in each bag, and for actuating the registering mechanism to indicate the amount of grain in each bag and the number of bags filled.

in the accompanying drawings, Figure 1 is aperspective view of a structure embodying my improvements; and Fi 2 the same view, the front of the casing being removed to disclose the interior arrangement of devices con tained in said structure.

A represents ataperin g case, which is located at the side of the upper portion of a vertical shaft, B. The lower portion of the shaft B is opened at one side, from which opening extends a receiving trough or receptacle, 0. A shaft, b, is located transversely across the vertical shaft B, as indicated in Fig. 2, and has bearings in the side of said shaft 13, so that the shaft I) projects at one end and has keyed thereon a beveled pinion, c. A shaft, 0, is jonrnaled on the upper side of the shaft B in any suitable bearings secured on the face of said shaft,- and so that a beveled pinion, c

carried by said shaft 0, will mesh with the beveled pinion c, and drive the same and its shaft 1) upon motion being imparted to a bandwheel, 0 located at the other end of the shaft 0. Two parallel-grooved pulleys, e e, are

keyed on the shaft 0, to permit endless chains or belts c to be passed around the said pulleys and around similar pulleys on a shaft, f, transversely located in the lower portion of the shaft B and bearing in the sides thereof. The belts e are spanned by a series of elevator buckets or carriers, f. A curved guard or shield, g, is extended across the upper portion of the shaft- B, and the said guard has pivotallysecnred to its center a chute or spout, g, which is contracted toward its lower end, as shown in Fig. 2. The major portion of the sides of the case A are inclined, as shown, and within the said case A are two partitions, h h, which converge toward each other and meet at their top, as shown in Fig. 2, and are arranged parallel with the sides of the case A, to form diverging inclined ducts or passages m, which are continued or extended by the vertical portions a of the case and the vertical port-ions 72. of the partitions h h. A horizontal plate, I), which forms the bottom of the case A, has centrally depending from the under side thereof an eye-loop,i, to which is pivotally secured the inner end of two rods,jj, which extend through vertical slots formed in the lower portions of the plates h 1L3. The projectingportionsofthc rods j are formed into hooks j Hooks j are formed on the. outer lower edge of the vertical side sections a, and from said hooks j and the hook-projecting portions j of the rods jj are suspended platforms E E, by means of cords or cables j.

()n the upper side of the bottom D, and near each plate h, is located a bracket, 7c, in which pivotally rest the trun zions k of a scale-beam, F, which carries a suitable poise, W, and which is connected at a point near its trunnions to the rods jj by a link-connection, 7c. The forward ends of the beams play in guide-links M, which are secured centrally on the upper side of the bottom D. A second horizontal plate, D, is secured parallel with J the bottom D, between the vertical plates It and above the scale-beams F. A depending loop suspended from the under side of the hor:z0ntal plate D, above each scale-beam,

, has centrally pivoted thereto a rod, 1, the inner end of which is connected to the inner end of the scale-beam below by a link, i, the outeren d of said rod l being connected by a flexible connection, P, with one end of abcll-crank lever, Z

pivoted in a slot at the upper end of the inclined side of the case A. The other end of the bell-crank lever is connected by a rod, m, to the lower contracted portion of the chute g. A dial or disk, G, is centrally pivoted above the plate I), and is graduated and provided on its face with a series of divisions indicating, respectively,ten units each. Thcmargin of the disk between the divisions is provided with a series of smaller figures, a, designed to indicate unit fractions of the divisions. The periphery of the disk G is provided with a notch corresponding with each divisionmark, and into said notches engage fingers 0, which are connected at their lower ends to the rods 1, as indicated in Fig. 2, and extend through perforations in said plate 1). A rod, is supported between the plates It It above the disk G, and has suspended thereon by means of loops a rectangular plate, p, which is divided off into a series of divisions, each provided with a figure or mnnerical character, which figures begin at one end of the plate and run successively up to any desired number. The bottom edge of the plate 2) is provided with a series of teeth, one of which is adapted to be engaged by a spur, g, on the disk G at each complete revolution of the disk, so as to advance or move the plate p one space. The springs 11 serve to normally hold the rolls a at the inner ends of the slots 1, and thereby maintain each scale-beam in its proper horizontal position.

\Vhile the arrangement of figures and numbers on the disk G and plate p have not been specifically described, it is sutficient to state that the numbers on the disk Gr between the dividing-lines thereon indicate, if desirable, the amount of grain contained in each sack, which, upon becoming tilled, rotates the disk one notch, which thereby operates upon the plate 2), as previously set forth, to move the same, and thus effect a total registration or tally of the amounts of the sacks being filled.

The operation of the device is as follows: The bags are placed on the platforms E E between the suspending-cablesj, and the poise 7c of each scale-beam F adjusted thereon so as to insure the operation of the scale when the desired quantity of grain has been placed in the bag which said scale registers. The parts being in the position illustrated in Fig.

.7' j beneath.

2, the grain is placed in the trough or receptacle (1 the endless belt is driven by the pulley and gear-connections, hcreinbct'orc explained, so that the buckets or carriers j" of said endless belt take the grain from the trough and elevate the same so as to dump it into the chute g, which discharges it onto the 1 plate h, from whence it passes to the bag on theplattorml l. Vhen a sut'ticientquantityhas been passed into the bag to counterbalance the poise on the scale-beam F of said platform E, the inner end of the scale-beam will be thrown up to move up the inner end of its rod l, depress the outer end of said rod, effecting the descent of the connections I? and the conr sequent movement of its bellcrank lever Z to throw the chute g into a position to discharge the grain onto the plate h when the forego ing operation is repeated with respect to the bag on the platform E. As each rod t is moved in consequence of its particular bag becoming tilled, it operates its linger 0 to rotate the disk one space in consequence of the pawlandratchet action of said finger in connection with the notched periphery of said disk G. The revolution of the disk G one notch or division represents the completion of the filling operation of one bag. There being ten divisions or notches on the said disk, its complete revolution, advancing the plate 3), indicates the completion of a series of ten bags. As the fingers 0 of the intermediate devices of the platforms, E E operate altei= nately on the notched disk G, of course the advancement otsaid disk represents, first, the filling of one-bag, and the successive movement the completion of the filling of the other bag. The rod of each scale F is formed into a rectangular slot, t, to receive a roller, 11, which is connected by a link, t), to the rods 3y this arrangement, when the rods j j are operated by the weight of the grain to tilt either of the scale-beams the roller it rolls back in the slot t of the said beam away from the fulcrum otsaid beam, and affords a greater purchase to move the pivotal spout, and insures a quick and positive throw.

By having a plurality of scale devices, as described, each adjustable and operating in dependently of each other, they can each be readily adjusted to respectively operate 011 receiving different weights or quantities of grain.

I claim- 1. The combination, in a grainweighing and bagging machine, of devices for supporting two bags or other receptacles to be filled with the grain, a movable discharge-chute located above the same so as to direct grain alternately into one bag or the other, a plurality of intermediate devices indepcndentlv connecting the chute with the bag-supporting devices and adapted to be adjusted to alternately operate and change the position of the chute upon the successive filling of the bags with different quantities of grain, substair tially as set forth.

2. The combinatiomin a grain-weighing and registering apparatus, of one or more beams suitably 't'ulcrunied and provided with poises, bag-supporting devices, each carrying a link connected to one of said beams by means of a roller playing in a slot in saidbeam, substantially as set forth.

In testimony whereof I at'tix my signature in presence of two witnesses.
